1997-1998 for BMW 528i 11781427884 O2 Sensor

This O2 sensor harness is a simple, effective fix. Installation was straightforward and it solved my open loop issue perfectly. Great value and works as advertised.

Fixed my rough idle and check engine light. Easy to install and the truck runs smoothly again.

This NOx sensor fit my Silverado perfectly. Easy plug-and-play install, cleared the fault code right away. It’s been running smooth for months. Great OEM replacement.

Good performance so far.

Happy with this accessory.
